What are the roles of history? what is the importance of history.
- To study the disease trend since past.
- Community diagnosis.
- Planning and evaluation of health services.
- Evaluation of a new therapy or a new health measure.
- Determining the risk to an individual.
- Identification of syndromes.
- Filling in the gaps in the natural history of the disease.
Epidemiology is the study of disease in populations. … Epidemiological methods are used for disease surveillance to identify which hazards are the most important. Epidemiological studies are also used to identify risk factors which may represent critical control points in the food production system.
In the mid-1980s, five major tasks of epidemiology in public health practice were identified: public health surveillance, field investigation, analytic studies, evaluation, and linkages.
For community diagnosis of the presence, nature and distribution of health and disease among the population, and the dimensions of these in incidence, prevalence, and mortality; taking into account that society is changing and health problems are changing. To study the workings of health services.
Epidemiology has an important clinical impact for it can be used to understand the pathogenesis of diseases, improve diagnostic accuracy, help the patient to reduce risk factors and the physician to choose the correct therapeutic approach.
Epidemiologists study outbreaks of diseases, the causes, locations, and how various communities are affected, utilizing relative information to aid in the prevention of future outbreaks. Epidemiologists help to keep the public informed of methods to maintain and improve public health.
The difference is that epidemiologists tend to use synonyms for the 5 W’s: diagnosis or health event (what), person (who), place (where), time (when), and causes, risk factors, and modes of transmission (why/how).
Environmental epidemiology is one of the most important tools used in environmental management decision making owing to its capacity to assess and monitor environmental hazards in different settings and quantify their health impact on the population at risk.
By definition, epidemiology is the study (scientific, systematic, and data-driven) of the distribution (frequency, pattern) and determinants (causes, risk factors) of health-related states and events (not just diseases) in specified populations (neighborhood, school, city, state, country, global).
Public health workers use epidemiologic principles as the foundation for disease surveillance and investigation activities. Epidemiology is the study of the distribution and determinants of health-related states or events in specified populations, and the application of this study to the control of health problems.
Conclusion: Epidemiological studies can potentially offer considerable benefits to the way nurses incorporate health-related practices into their professional role. Research also offers a valuable opportunity for the nursing profession to become more active in helping to determine health policy issues.
Environmental epidemiologists study health effects with known or suspected ties to environmental contaminants. They study developmental delays, neurological disorders, cardio-pulmonary diseases, and other health effects in people of all ages.
Epidemiologic studies fall into two categories: experimental and observational.
Epidemiological methods are used to detect infectious pathogens, determine disease causality, understand pathogenesis and the natural history of infections as well as ways to devise effective interventions for their prevention and control.
Principles of Epidemiology for Advanced Nursing Practice: A Population Health Perspective teaches nurses how to critically analyze epidemiological data so they become skilled at creating evidence-based interventions which will contribute to the improvement of population health outcomes overall.
- Analyze data and find conclusions.
- Create a plan of action for potential health crises.
- Create reports detailing potential threats.
- Give presentations to policy makers.
- Communicate with policy makers on public health.
- Manage multiple projects at once.
- Communication skills. Epidemiologists must use their speaking and writing skills to inform the public and community leaders of public health risks. …
- Critical-thinking skills. …
- Detail oriented. …
- Math and statistical skills. …
- Teaching skills.
No. It is generally classified as part of medicine and the life sciences. If you count it as a social science, it still isn’t hard science and thus not STEM.
To become an Epidemiologist, you can pursue courses like B.Sc in Epidemiology, B.Sc or Bachelor of Public Health or relevant. As additional qualification, you can also pursue M.Sc or Master in Public Health/Epidemiology or even a PhD in Epidemiology.
